After publication of the original article (Mahrous et al. 2020), we were notified that Fig. 1 is incorrect. The corresponding author uploaded the wrong figure by mistake. Below the correct version of Fig 1.

Fig. 1
figure 1

Agarose gel electrophoresis of hepcidin 1 (264 bp, left panel) and hepcidin 2 (375 bp, right panel)-PCR fragment. M, 100 bp DNA ladder

The correct Fig. 1 is below:

Furthermore, the hepcidin 2 PCR product in the 3 investigated species is 375 bp as it was indicated in Fig. 6 and GeneBank records with accession numbers MH651359.1, MH651363.1, andMH651367.1. The hepcidin 2 PCR product length in the last line in the right column within page 3 and the fourth line in the right column within page 5 should be corrected to 375 bp, instead of 273 bp.

The corresponding author has confirmed this correction will not make any change to the conclusion of their original research. The authors apologize for any inconvenience that this may have caused.
